The programmer of the c64 version reckoned he was burgled one night, and the theif stole the 90% complete code for the game, which the publishers then used as an excuse never to release the c64 version. Nothing to do with the st, just thought u'd like to know thats all. ps. it was zzap64 that reported the story.
This is a great two player game, grab a friend and try it now! The only problem is that it gets a bit easy, getting 99 credits at the end of the giant world can really kill the game.
